Abstract: A process for preparing a polyurea reaction injection molded (RIM) elastomer is described. A hindered polyetherpolyamine is first obtained by reacting a polyol having two or more hydroxyl groups with an effective amount of long chain alkyl epoxide to give an at least partially hindered intermediate having hydroxyl terminations; and then aminating at least one of the hydroxyl terminations on the intermediate to primary amine groups to give an at least partially hindered polyetherpolyamine. The hindered polyetherpolyamine is then reacted with a polyisocyanate in the optional presence of a catalyst to give a polyurea RIM elastomer. The long chain alkyl group provides steric hindrance to the primary aliphatic amine group, which slows down the reactivity of the amine. The slower reactivity of the amine group is useful in RIM and RRIM compositions since it allows for longer shot or flow times, which in turn permit larger parts to be made from existing equipment.

Abstract: Synthetic lubricant base stocks may be prepared in good yield by oligomerizing linear olefin monomers using certain acidic calcium montmorillonite clay catalysts. When the oligomers are prepared at a temperature greater than about 200.degree. C., and any unreacted linear olefin monomer is removed, oligomers having an iodine value less than about 3 mg/g are obtained. An even lower iodine value is obtained when a hydrocarbon possessing a tertiary hydrogen is mixed with the linear olefin feed, and the mixture is contacted with the clay at a temperature greater than about 200.degree. C. Little or no hydrogenation may be required of oligomers prepared in this manner to obtain base stocks suitable for use as synthetic lubricants.
